GRAIN-SEPARATO'R.

SPECIFICATION forming part of Letters Patent No. 469,827, dated March 1,1892. Application led November 10, 1891. Serial No. 411,470. (No model.)

To a/ZZ whom t may concern.'

Be it known that I, WILLIAM H. ScHULTE, a citizen of the United States,residing at H opedale, in the county of Tazewell and State of Illinois,have invented certain new and useful Improvements in GrainSeparators;and I do hereby declare the following to be a full, clear, and exactdescription of the invention,

such as will en'able others skilled in the art tov which it appertainsto Amake and use the same.

The invention relates to grain-separators which have rotary wirescreens, such a one being described in Patent No. 215,078, granted toSturgeon on the 6th of May, 1879.

My invention consists of the particular means by which I raise or lowerone end of the screen-shaft, so as to regulate the inclination of thescreen to suit the grain or seed which is to be separated; also, theparticular means which are employed by me to jar or shake the reel whenso desired.

Figure l of the drawings isa vertical longitudinal section of theseparator; Fig. 2, a detail vertical sectional view of the device forraising or lowering the discharge end of the reel or screen shaft. Fig.3is a detail view of the hand-piece, together with its connections, whichare in section; Fig. 4, a detail side elevation of the knocker and thestrip against which it turns, and Fig. 5 a detail view of the shaft andshowing the annular groove therein.

In the drawings, A represents the discharge end of the case, slotted ata to allow the flat part b of the handpiece B to pass therethrough, asit also passes through the slot c of an outside plate C, which is madefast to case end A. On this plate C is made a rack or series of notcheson each side of the slot c. The piece B has a tubular portion b', Whoseshoulders abut against plate C, while through the tube extends a rod D,which has a {ingerdisk d on the outside end and a cross-pin d on theinner end. Around the rod and between its ends is arranged a spiralspring E, which holds the cross -pin in the rack or notches 011 plateC.On the inner end of the hand-piece B is secured a vertical slide F,which is moved in the guides G G on the case end A. At the top of thisslide is an open bearing to receive one journal of the screen-shaft H.When it is desired to change the inclination of the screen, one inger ispressed on the disk d,while the slide F is carried up or down to makethe adjustment. The spring on rodD will then draw the crosspin d in theopposite grooves of plate C and thus hold the slide securely.

On the shaft H, near the hopper, I place a polygonal disk to turn Withthe shaft against the strip J. As the polygon I turns it jars thescreen, so as to dislodge the seeds which may stick vin the intersticesof the wire reel, the shaft H risingin the slot a. The knocker may ormay not be used, as the shaft H has a groove h.

'Vhen itis desired to use the knocker, move the hopper end or theelevated end of shaft up to the polygonal disk, when the latter willstrike or jar the reel or screen. The shaftgroove h receives the bearingof slide F, or the screen, which is always on an incline, would slipback. The wire screen is made somewhat shorter than the inside of thecase, which allows the higher end of the reel to be moved up, so as tobe locked on the bearing of slide F. Without making the groove h in theshaftI could not use the knocker; but with it I can operate the knockeror not, as circumstances make it expedient or otherwise. I have,however, tested the whole invention in av full-sized grain-separator,and both features thereof have been found to work Well. Hence I havedeemed it but right that I should obtain protection under the patent lawfor what must inure to the benefit of the public.

Having thus described all that is necessary to a full understanding ofmy invention,what I claim as new, and desire to protect by LettersPatent, is-

In a grain-separator, the combination, with the end A, having thevertical slot a, of the hand-piece B, flat at b and tubular at '11', theoutside plate C, having slot c and notches on each side thereof, the rodD, having a disk d at one end and a cross-pin d at the other, the spiralspring E around said rod, and the slide F, having an open bearing at thetop, all

substantially as shown, and for the purpose specified.

In testimony whereof I afiix my signature in presence of two witnesses.
